GNSS Applications to Assess Performance in Olympic Sailors: Laser Class. Applied Sciences. 2021; 11(1):264.http://hdl.handle.net/10668/4080Laser class is an Olympic sport in which technical and tactical variables are very important in the performance of the sailor. However, the variables that determine performance in a regatta have not been studied, and less so with Olympic sailors. Therefore, the main objectives of this study are to analyze the technical and tactical variables that differentiate sailors based on their level of performance and sex and determine the most important courses in a regatta. The sample consists of 159 Olympic sailors (67 females) of the Laser class, who participated in a World Cup. Velocity made good (VMG), distance, and maneuvers were evaluated using Global Navigation Satellite System (GNSS) devices in the upwind, downwind, and broad reach courses. VMG in upwind and downwind is the technical variable that determines performance in the Laser class. The VMG is decisive in the performance of elite female sailors in the upwind, downwind, and broad reach courses, while in elite male sailors, performance is mainly influenced by speed in upwind and downwind and the distance covered in upwind. The maneuvers do not determine sailing performance in any of the courses of a regatta.enAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/GNSSPerformanceDinghy sailingOlympic sailorsPhysical fitnessRendimientoRayos láserPersonal militarAptitud físicaMedical Subject Headings::Check Tags::MaleMedical Subject Headings::Check Tags::FemaleMedical Subject Headings::Persons::Persons::Occupational Groups::Military PersonnelMedical Subject Headings::Analytical, Diagnostic and Therapeutic Techniques and Equipment::Equipment and Supplies::Radiation Equipment and Supplies::LasersMedical Subject Headings::Technology and Food and Beverages::Technology, Industry, and Agriculture::Transportation::ShipsMedical Subject Headings::Phenomena and Processes::Metabolic Phenomena::Metabolism::AnaerobiosisMedical Subject Headings::Phenomena and Processes::Musculoskeletal and Neural Physiological Phenomena::Musculoskeletal Physiological Phenomena::Physical FitnessMedical Subject Headings::Persons::Persons::AthletesMedical Subject Headings::Phenomena and Processes::Biological Phenomena::Ecological and Environmental Phenomena::Meteorological Concepts::Weatherresearch articleAcceso abierto10.3390/app110102642076-3417
